SPINDLE FOR RING-SPINNING FRAMES.

- SPECIFICATION formingpart of Letters Patent N0. 288,230, dated November 13, 1883.

A Application filed November 18, 1862. (No model.)

To all? whom it may concern:

Be it known that I, J AMES R. GRAY, a citizen of the United States, residing at Ayer, in the county of Middlesexand State of Massachusetts, have invented a newand useful Improvement in Spindles for Ring Spinning Frames; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being bad to the accompanying drawings.

.Myinvention has for its object to providea spindle that shall be entirely free from the evil effects due to the tension of the driving-band,

and be able to yield with suchfreedom in all 5 easily and without restraint assume any direction of rotation required to accommodate all variations in the distribution of its bobbinload occurring in practical use.

It consists, essentially, in cutting the spindle into two separate parts, and then inter posing between such parts an intermediate flexible connectionadapted to impart rotation from the lower to the upper part, and at the same time allow the upper part to assume and maintain an independent axis of rotation with relation to the lower part, such upper part, which alone receives and supports the bobbin, being supported within the bolster by a yielding bushing, which allows it to move laterally throughout its entire length.

Referring to the accompanying drawings, Figure l is an external elevation of my improved spindle as applied to the usual bolster-rail of aspinning-frarne; Fig. 2, a sectional elevation of the same, and Fig. 3 a plan or top View of the whirl-spindle p.

B is a holster secured to the rail R by the nutbracket D, whichalso carries the step orverspindle taking its lateral support within the lower end of the bolster B, and being driven by the whirl 10, which is preferably made to sleeve the lower end of the bolster, as shown.

The upper bobbin-carrying spindle, A, revolves within the steadying-bushing e, which is loosely fitted within the bolster, and allows the spindle A to move laterally throughout its entire length, thus enabling the spindle to change the direction of its axis of rotation and accommodate itself to an unequally-distributlateral directions when running that it may tical support of the whirl-spindle p, the whirled bobbinload, 'or, in other words, to center itself, upon thewell-known principle of a childs top. In order thatthe spindle A'may thus center itself, as described, and at the same time receive rotary motion from the whirlspindle, the two are connected or locked together by means of the flexible connection k, which is preferably made from flat wire or sheet metal of such width that it will loosely 6 fit within the bore 1', formed in the butt of the spindle A, and of such a thickness thatit will also loosely fit the slots 0, Fig. 3, formed across the upper end of the whirl-spindle, and a, formed across the plug (1, which is driven into 6 the bore a. To render the connection more flexible in its operation, it is twisted spirally to a quarter-turn, bringing its two ends into vertical planes which are at right angles to each other, and the operation of the parts he 7Q comes similar to that of the well-known universaljoint.

The slot c'may be located at or near the lower end of the spindle A and the bore a omitted; but by locating the slot as shown the parts are brought into a more compact form, and the connection k can be made longer, and consequently more flexible in its opera- 'tion.

The steadying-bushing e is loosely locked s within the bolster by the retainingscrew S, which also acts, in conjunction with the shoulder h, to prevent the spindlefrom being raised when the bobbin is doffed.

Oil is supplied at the oil-trough tand passes through the educt r to the interior of the bolster.
